- Electronic speed controller 400V~60A
Exception: In order to be able to install an electronic speed control for the double banked models fitted with fans with a total electri-
cal input exceeding 60A, it is necessary to use two 40A controllers. The installation of the two devices must
be carried out according to the CONN diagram, connecting one speed controller per bank.
All the safety and installation procedures pertaining to other models also remain valid in this instance.
Important:
the optional controller devices to be used must be requested solely from the manufacturer following the relative order codes.
Should the machinery be modified or tampered with, or should control devices other than those listed above be applied, the manufacturer
will decline any and all responsibility.
Cable diameters: The diameters of cables to be used for connecting the control devices must be:
- for the speed controller: equal or superior to the maximum nominal diameter of the power cable (see Tab. 1)
- for thermostats: equal to at least 2.5mm2 for single-phase models with 3 fans. 1.5mm2 for all other models (including three-phase)
All the connection cables accessible to the user must be double insulated sheathed cabling.
For the connection of the control regulation devices follow precisely the connection plan below: CONN DIAGRAMS
